Cartridge Heater

Cartridge Heaters

We design Cartridge heaters which are made by inserting it into the close fit hole which is bee drilled easily into the mold which contains solid platen. These cartridge heaters have a special feature to deliver superior heat transfer at a very standard and uniform temperature. Hence these industrial heaters are the most ideal ones which are used in a lot of applications which requires higher kilowatts. There are a lot of industries who make use of this heater for mold dyeing, sealing bars, platen heating and for various other purposes.

Crimped-On-Leads

Crimped-On Leads

A high temperature double crimp connects the MGT (450°C) leads to solid nickel pins. This construction is recommended for applications with high temperatures. Due to the rigid nickel pins, this construction is not recommended in applications where movement or flexing is encountered, or if sharp bends are required adjacent to the heater exit.

Swaged-in-Leads

Swaged in Leads

High temperature MGT (450°C) wire is internally connected and swaged in place. This construction is recommended for applications in which the leads must be bent at the exit point from the heater and where mild flexing may be found. For applications with continuous or more severe movement, we would recommend metal braid or armor cable.

Stainless-Steel-Braid

Stainless Steel Braid

High temperature MGT (450°C) wire is internally connected and swaged in place along with stainless steel braid. This construction offers protection against scratch and sharp edges. This is a very strong construction which offers full length flexibility. This construction is recommended in applications with flexing and where the leads must pass through metal openings or routed along metal components.

Stainless-Steel-Armoured-Cable-(Hose)

Stainless Steel Armoured Cable (Hose)

High temperature MGT (450°C) wire is internally connected and swaged in place along with stainless steel hose. This construction is recommended for applications in which the leads are subjected to scratch or run the risk of being tense. This is the strongest lead protection available and works well in moving or flexing applications.

Right-Angle-Fibreglass-Leads

Right Angle Fibreglass Leads

High temperature MGT (450°C) leads exiting at right angle to the sheath. This construction offers a compact design where space is limited. This construction is not recommended where abrasion or flexing is present.

Right-Angle-Stainless-Steel-Braid

Right Angle Stainless Steel Braid

Stainless steel braid over high temperature MGT (450°C) wire exiting at right angle to the sheath. This construction is recommended in applications with flexing and where the leads must pass through metal openings or routed along metal components. This construction is desirable when space is limited and it is not feasible to bend standard leads

Right-Angel-Stainless-Steel-Armour

Right Angel Stainless Steel Armour (Hose)

Stainless steel hose over high temperature MGT (450°C) wire exiting at right angle to the sheath. This is the strongest lead protection for use in applications where severe abrasion is present. These leads offer good flexibility and are good for moving or flexing applications.

Mounting-Flanges

Mounting Flanges

Mounting flanges are recommended for applications where vibration or movement may cause the heater to be disloged from its hole. Stainless steel flanges are available in a variety of sizes and configurations. The standard flange is round and is supplied with two mounting holes. For heaters 5/8″ diameter and under, the flange would be 1 1/2″ in diameter. For larger diameter heaters the standard flange would be 2.00″ in diameter.

OPTIONAL CONSTRUCTIONS

Teflon-End-Seal

Teflon End Seal

A Teflon plug is swaged in place along with Teflon leads. This construction resists oil and water to 250°C/480°F. There is a minimum of a 1.00″ unheated length at the lead end. Longer cold sections may be required if the watt density or operating temperature is high.

Screw-Terminals

Screw Terminals

Threaded stud terminals are supplied complete with high temperatue nuts and washers. Standard screw is #8-32. Available in 5/8″, 3/4″, 1″, 16 mm and 20mm diameters heaters.

Double-Ended-Terminals
Double-Ended-Terminals-2

Double Ended Terminals

These terminations are ideal for applications where wiring form both ends is required. A minimum cold section of 1″ is required for these leads.

Available Terminations

– Solid nickel pins
– Leadwires
– Threaded studs

Terminal-Boxes

Terminal Boxes

Terminal boxes are permanently attached to the heater sheath to provide excellent protection in a variety of environments.

Available Boxes

– General purpose sheet metal
– Moisture proof
– Cast aluminum explosion resistant

INTERNAL THERMOCOUPLES

Internal thermocouples are built into the heater assembly to monitor the internal or sheath temperatures. These are useful as high limit devices or in applications where space is at a premium. The power and sensor leads exit the sheath together and can be ordered with a variety of lead protections. Not all thermocouple configurations are available on smaller diameter heaters.

Type J and K calibrations are standard for the shown constructions.

Grounded-at-Disc-End

Grounded at Disc End

The thermocouple junction is grounded to the disc end of the heater. This construction is commonly used in hot runner applications. The disc end can be filled with silver solder and ground flat. This will ensure good contact when inserted into a flat end blind hole.

Ungrounded-at-Disc-End

Ungrounded at Disc End

The thermocouple junction is ungrounded and is located just behind the disc end. This will give a reference temperature of the part being heated.

Grounded-at-Centre

Grounded at Centre

The thermocouple junction is grounded to the sheath along the length of the heater. The standard location is at the center of the heater, but can be located anywhere along the lenght of the sheath. This construction will provide a quick response.

Ungrounded-at-Centre

Ungrounded at Centre

The thermocouple junction is ungrounded and is centered in the diameter of the sheath. The standard location is at the center of the heater, but can be located anywhere along the length of the sheath. Typically used as a high limit in air or vaccum applications.
